RE: [Xen-devel] xen bootup problem: unable to open an initial console

[Xin Zhao <zhaoxin@xxxxxxxxxxxxxx>]

Thanks for all follow-ups. I tried Nitin's solution, it worked for me. Now
I can boot 2.4.30-xen0 successfully. Since this approach is quite simple,
we can probably follow that. The only issue is that Nitin's description
seems to be wrong. Instead of doing "cp /dev/* /mnt/*", we might need to
do "cp /dev/* /mnt/dev/".
